RADIO COMMUNICATION SYSTEM AND POWER-SAVING METHOD THEREOF

A radio communication system comprises a parent node transmitting a beacon signal as one-to-many communication at every constant period, and a child node receiving the beacon signal, the parent node and the child node operating in synchronization with each other by using the beacon signal. The child...

Beschreibung
Zusammenfassung:	A radio communication system comprises a parent node transmitting a beacon signal as one-to-many communication at every constant period, and a child node receiving the beacon signal, the parent node and the child node operating in synchronization with each other by using the beacon signal. The child node transmits a schedule notification signal for providing notification of presence/absence of a schedule of data transmission to the parent node, within a predetermined time period between the beacon signals. The parent node transitions into a sleep state until a time of transmitting the next beacon signal, when the parent node cannot detect the schedule notification signal in the predetermined time period.
